【摘要】 可冲散擦拭材料常在湿法成网后经化学黏合或水刺加固而制成。但湿法成网和水刺加固耗水量较大，且多数化学黏合剂会造成严重的环境污染，因此节水的发泡成网工艺成为行业的研究热点。本研究采用发泡成网工艺，以秸秆纤维、木浆纤维和天丝纤维为原料，分别采用加入湿强剂聚酰胺聚胺表氯醇(PAE)和热熔纤维的增强方法，制备可冲散擦拭材料。比较PAE和热熔纤维制备的可冲散擦拭材料的性能发现：热熔/秸秆纤维试样的湿态强力更佳，同时具有一定的吸水性和透气性。综合考虑可冲散擦拭材料性能、制备成本及环保等因素，确定热熔/秸秆纤维试样中热熔纤维质量分数以30%为宜。在此条件下，热熔/秸秆纤维试样的湿态强力可达9.8 N,符合可冲散擦拭材料的湿强要求；透气率在126.3 mm/s;吸水率为814.7%;可分散百分比为72.3%,满足标准对可冲散产品可分散百分比的要求。研究结果以期为耐用型可冲散擦拭材料的研发提供新思路。更多还原

【Abstract】 Flushable wipes are typically manufactured via wet-laying followed by chemical bonding or hydroentangling. However, both wet-laying and hydroentangling consume significant amounts of water, and most chemical binders cause severe environmental pollution. Consequently, the water-saving foam-forming process has become a research hotspot in the industry. In this study, flushable wipes were prepared using a foam-forming process with straw fibers, wood pulp fibers, and Tencel fibers as raw materials. Two reinforcement methods were employed: the addition of the wet strength agent polyamide-polyamine-epichlorohydrin(PAE) and hot-melt fibers. A comparison of the effects of PAE and hot-melt fibers on the properties of the flushable wipes revealed that the hot-melt/straw fiber samples exhibited superior wet strength while maintaining specific water absorption and air permeability. Comprehensive considering factors such as performance, production cost, and environmental protection of the flushable wipes, it was determined that the optimal mass fraction of hot-melt fibers in the hot-melt/straw fiber samples was 30%. Under these conditions, the wet strength of the hot-melt/straw fiber sample reached 9.8 N, meeting the wet strength requirements for flushable wipes. Additionally, the air permeability was 126.3 mm/s, the water absorption rate was 814.7%, and the dispersibility percentage was 72.3%, satisfying the standard requirements for the dispersibility percentage of flushable products. These findings aim to provide new insights for the research and development of durable flushable wipes.更多还原
